Add ClientRequestHandler to initiate Paxos in convenient way: just send a string as the Paxos value to Proposer's role address by tools such as nc. e.g. echo hello | nc localhost 10000
Add the fixes I added after THAT version(589e7c31b7a1c323fdca35ba6db1f730caa154ea) in da_project:
- Add ProposerNumber's constructor with specified number.
- Add iAmLeader property and resendPrepareMessage method in Proposer.
- Add leader behaviours in Proposer.
- Fix Proposer logic when late AcceptedMessage cause wrong reset.
